Simulation Particles are generated at the center of target Randomly generation points are moved in the target thickness Fitted by the single landau function K + : HKS GEANT4 E’ : POSI GEANT4 K + : HKS GEANT4 E’ : POSI GEANT4 EXAMPLE (POSI, 12 C, 100mg/cm 2 )
Results of Energy Loss TargetK + (1.2 GeV)e’ (3.0 GeV) 208 Pb 50mg/cm ± ± Pb 100mg/cm ± ± Pb 200mg/cm ± ± C 100mg/cm ± ± 0.06 Unit : keV These values are peak center values derived by the fitting
Results of Straggling (Rough estimations) TargetK + (1.2 GeV)e’ (3.0 GeV) 208 Pb 50mg/cm Pb 100mg/cm Pb 200mg/cm C 100mg/cm Unit : keV These values are derived just by multiplying the energy loss values by 2
